IMPROVEMENT IN JolsT-sEATs.

Specification forming partof Letters Patent No. 152,283, dated June 23, 1874; application filed May 1S, 1874.

To all whom t may concern:

Beit known that I, WILLIAM H. DnAKE, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Joist- Seats, of which the following is a specification:

The object rof the present invention is to provide securer means for holding the ends of lioists in brick and stone buildings. The nature of this invention consists in the novel construction of joist seats, which are provided with semi-dovet-ailed bearn gs for the joists to bear in, and with anchors on the sides thereof to hold the seats in a wall, as the whole is hereinafter fully described and shown.

In the drawings, Figure l is a perspective representation of my improvement in joistseats removed from the wall of a building. Fig. 2 shows the joist-seat in the wall in section. Fig. 3 is a side elevation of the joistseat in a wall.

A A Arepresent the vertical sides of my improvement in joist seats. B is the back. C is the inclined bottom, and D E are the anchors, which hold the device in the wall of a building.

The device as a whole, as shown in Fig. l, is to be made of burned clay, similar to brick material, cement, or metal, or other suitable material-as, for instance, terra cotta. The height of the sides are to correspond to the depth of thel joist used, and their distance apart is to correspond to the thickness of the joist. The bottom C on its upper side is inclined outward and downward, as shown, in order that every joist in a building shall anchor fast, and so that the greater the weight the firmer the joists will hold to the seats. That the seats may be firmly fastened in thel wall G, anchors D E at the lower end thereof' rest 011 the joist-course, and are held firmly thereon by mea-ns of the brick laid in the wall.

In practice the seats can be set on the joistcourse and bricked in, or partly bricked in, before the joists are set, or the joists F can be sized on the sides and semi-dovetailed 011 the ends of the lower edges, placed in the seats, and the latter set on the joist-course, and then bricked in.

By the use of the seats thus constructed and set anchor-bolts are unnecessary, while at the same time the leverage by the joists ruiming into the wall too far is obviated, and dry rot in the ends of the joists is prevented. Sockets have been before used to sustain the ends of joists, therefore, I confine myself' to the construction ofthe seat as shown.

I claim and desire to secure by Letters Patent of the United States- Seats for joists consisting of the vertical sides and back A B, inclined bottom C, and anchors D E, as and for the purpose described and shown.
